自适应交互多模型火控跟踪算法

以舰载近程防空火控系统的跟踪预测为背景,提出一种自适应的交互式多模型跟踪算法,模型集合取为"当前"统计模型和匀速直线模型.该算法采用后验估计的方法在线辩识及自适应调整上述两个模型的噪声方差,并且采用加权系数限定准则,实现机动目标运动模式与模型集合的自适应.仿真计算证明了该模型算法的有效性.

Adaptive Interactive Multi-model Tracking Algorithm for Fire Control

Taking the short rang ship-base anticraft fire control system as a background,the author put forward a adaptive interactive multi-model tracking algorithm,the "current" statistical model and even speed linear motion model are taken as a set of models.This algorithm adopts the posterior estimation for on-line identification and adoptively adjusts the noise variance of above-mentioned two models,and uses the limiting weighting coefficiens for realise an adaptation of maneuverable target's motion mode with model set.The simulation results proved that this model algorithm is efficient.
